Abstract: The present application provides a packaged gate drive circuit having a transformer. The transformer which is used to transfer both signals and power from a primary side to a secondary side. The windings of the transformer are formed using a combination of tracks and wirebond wires. The transformer is positioned in a well formed using a first insulating material and covered with a second insulating material.
